DOOR-LOCK.

To all whom it may concern:

JAMES R. Cones, citizens of the United States, and residents of New York, in the county of New York and State of New York, and of Dinsmore, in the county of Duval and State of Florida, respectively, have invented certain new and useful Improvements in Door-Locks, of which the following is a specification.

This invention relates to door locks and is an improvement over the form shown and described in the application for Letters Patent of the United States filed by Herman Rein on the 7th day of March, 1916, Serial No. 82,599, and some of the main objects are to provide such locks which are positively burglanproof, which are adapted to use either as mortise or side locks, which are adapted for use on either right or left hand doors, and wherein the several parts are reversible and interchangeable.

Our invention is fully described in the following specification, of which the accompanying'drawings form a part, in which like characters refer to like parts in each of the views, and in which Figure 1 is a vertical section taken through a lock constructed in accordance with our invention. as on the line 1-1 of Fig. 3, with the door locked;

Fig. 2 is a similar view with the lock bolt retracted,

Fig. 3 1s a section taken on the line 3 -3 of Fig. 2;

Fig. 4 is a section taken on the line 4-4 of Fig. 2;

Fig. 5 is a section taken on the line 55 of Fig. 2; and Figs. 6 to 9, inclusive,.are sections taken on the line 6-6 of Fi 2 and showing progressive steps in the It projection into locking position.

Referring to the drawings 10 represents a door jamb havinga recess 11 therein having a striking-plate 12 therein and thereover provided with an an lar passage 13 and with a horizontal en argement forming shoulders 14, Figs. 3 and 6 to 9, inclusive, these shoulders forming an important feature of the lock.

At 15 is shown a door having a mortise 16 for the lock casing 17 within which the operable. parts of the invention are located, and said parts may be controlled by either Specification of Letters Patent.

Application filed May 18, 1916. Serial N 98,397.

"knobs or by a key, knob shanks 18 and 19 belng showr, as well as a cylinder lock 20, but no effort has been made to illustrate any means i or preventing knob' rotation as many forms thereof are now in use and may be adapted to our lock.

Each kno') shank carries a roll-back, 21 for the shar k '18 and 22 for the shank 19, independent y operable 'upon a sear 23 guided between lugs 24 on the casing back, the cylinder lock also acting on said sear by means of a roll-back 25, a ainst the action of a ;pring 26 which ten s to force said sear fol wardly toward the free edge of the door.

The forw: rd end of the sear 23 is bifurcated to span two identical though reversely arranged b(lt members 27 and 28 freely mova 1e up )Il a-pivot 29 carried by said sear, the outer ends of said bolt members being vertictlly thickened to jointly equal the vertical diameter of the'sear, and each of said bolt members carries a tooth 30 adapted to )ear. against the inner side of the edge plate 31 of the lock casing when the bolt is in extreme forward position, Fig. 1.

By reference to Fi s. 6 to 9, inclusive, it will be seen that eaeili bolt member is cut away at the front thereof to provide a book 32 adapted, as shown in Figs. 8 and 9, to engage with the striking-plate shoulders 14, and the inner ends of said bolt members are cut away to form shoulders 33 bearing against a relatively long stationary stop 31 on each inner side of the casing, though in difierent hor zontal planes, in the inner position of the Jolt, and said stops also serve as guides for the bolt members as will be later explair. ed.

-The bolt members 27 and28 are joined, forwardly oi the pin or pivot 29, by means of a pivot 35 permitting rotary movement ofeach bolt member and so located as to have its axis in the plane of the free edge of the door when the bolt is in outermost position whereby it will be impossible for a house-breake r to break either the bolt memdirected slots 36 having, each, an inclined portion 36 and a portion 36 substantially parallel with the sides of the lock casing, the pivot pin 29 being passed through said slots and being at the inner ends of the inclined portions with the bolt in retracted position.

Arranged above the bolt members is a detent 37 of bell-crank form pivoted at 38, the pivot 38 being detachably held in the front edge'of the lock casing and in one or the other of two lugs 39 and 40 according to whether the door is left or right hand, and the inner-end ofsaid pivot 38 isangularly bent and locked against longitudinal movement by means of one or the other of two stops 41 and-42, Fig. 3.

The detent 37 has two identical arms or leaf members in order to make the same reversible and is preferably gravity operated, the lower arm having a plurality of notches 43 for the reception of the tooth 30 of the uppermost bolt member, Fig. 2, whereby the bolt is held in retracted position when said tooth is in the innermost notch but, when the detent is, rocked on its pivot, the tooth 30 is released and the boltis shot out by means of the spring 26, Fig. 1.

The upperarm of the detent 37 bears against a carrier 44 of circular form in cross section and slidable in asimilarly shaped channel 45 in the casing 17 and door 15, said carrier having. a screw threaded thereinto, shown at 46 F i 4, in turn carryin an angular button 4 on its outer end sli ably mounted in a guide 48 detachably secured to the side of the door facing the direction of closing movement, said carrier, screw, and button being normally held in outermost position by means of the detent 37 when the latter is in tooth engaging position, and .it will be noted that the button 47 is normally flush with the surface of the door and may be adjusted for doors of varying thicknesses by means of the screw 46.

The door stop 19 of the door jamb is pro vided with a post 50 in the. position of the button'47 when the door is closed whereby the 'button is forced inwardly of the door to rock the detent 37 and thus release the bolt tooth 30 and thereby permit the spring 26 to force the bolt outwardly of the door and into the jamb, and said bolt may be retra'ted by the knobs or 'by the key in the cylinder lock although, as hereinbefore stated, suitable means may be provided to prevent rotation of the outer knob when desired.

The operation of the bolt members is clearly shown in Figs. 6 to 9, inclusive, the first showing tionsand, w 37 to release the bolt the sear 23 moves for- "wardly and carries the pivot pih'29 therewith; Inasmuch as the stops 34 will not permit lateral movement of the inner ends the parts in door- 0 'n '-posi-' en the post 50 rocks t 1e detent of the bolt members, the pivot pin 29 cannot move in the slots 36 and the bolt members are also carried forwardly into the positions shown in Fi 7 just clearing the stops 34. The inner en s of the bolt members may now move laterally and this movement is produced by the pivot pin 29 sliding along the inclined portions 36- of the two slots 36 until the two ortions 36" a proximately register and thls rocking of t e bolt members on their pivot 35 forces the outer ends laterally in o posite directions to en age the hooks 32Witl2 the shoulders 14 in t e striking-pla'te, and continued movement of the sear forces the pivot pin 29 into the portions 36 of the slots and thus prevents any rocking of the boltmembers on the pivot 35 and forestalls any attempt to rock the said members by means of an instrument inserted between the door and jamb.

Upon retraction of the sear, by knob or key, the pivot pin 29 first moves out of the registering portions 36 of the slots- 36 and then moves along the inclined portions 36, the bolt members being'thus rocked on the pivot 35 into the positions shown in Fig. 7, after which the bolt members are carried rearwardly to innermost positions, the inner ends thereof having been cleared from the forward ends of the stops 34, these stops limiting rearward movement of the bolt members, in retracted positions, preventing retracting when in their outermost positions, and preventing lateral movement thereof when in retracted positions, and the uppermost tooth 30 holds the parts in retracted position whereas both teeth 30 limit forward movement of the bolt members.

From the foregoin it will be seen that the bolt is positively lmmune from any exterior attempt to retract the same by means of any implement introduced between the door and jamb, and the pivot 35 being in the plane of the narrow space between the .door and jamb no possibility of rocking surface inthe position of the button 47, and V the post 50 is practically buried in the angle of the stop 49 whereby no injury to clothing or to the body of a person can occur by catching on the same, and, as stated, the lock may be adapted to various uses other than that shown.
